I am starting to question the credibility of AllKpop. First of all, this is a practice video for their concert last week. AllKpop is making it as if it is something new.. 2nd. The grammar.. "Like in their previous cover, the girls give an interview before the perform the cover of IOI's hit song"OMG... Can't you do some research and read before posting? Whoever made this article needs to be re-evaluated. Like seriously..
